The invention briefly described consists of a grenade support comprising a bracket or plate adapted to be secured to a wall or other supporting structure, a pair of resilient supporting members adapted to embrace the grenade and form the support therefor and means including a fusible element engaging the supporting members and retaining them under tension. In the form of the invention shown, the means for holding or retaining the supporting members under tension is located on the opposite side of the grenade from the bracket or plate on which the members are mounted and when the fusible element melts, the resilient supports spring apart, permitting the grenade to drop. The grenade is preferably formed of glass or other frangible material and is broken. when its strikes the floor. thereby freeing thefire extinguishing liquid, such as carbon tetrachloride, contained In the particular form 0 shown there is illustrated a f the invention plate or bracket 10 having an opening 11 therein adapted to receive a screw or other retaining member.

The

plate is preferably formed of sheet metal and has punched therefrom or secured thereto two sets of pivot lugs or loops 13 and 14.

The grenade is supported in a pair of longitudinally curved supporting members 16 and 17 formed of resilient material, such as resilient wire stock. These members have substantially straight end portions 20 and 21 which are disposed in parallel relation to each other when the supporting members are placed under tension as shown in Fig. 3.

The members 16 and 17 are bent laterally as shown at 22 and 23 and at lateral portions,

body portion of the supporti the ends of the are bent downwardly or at substantially right angles to the plane of the ng members.

The downwardly extending portions 25 are pivoted in the lugs or loops 13 and 141. The

bends 22 and 23 are so formed that in order to bring the body portions of the members 16 and 17 to the position shown in Fig. 3, or to the position in which they are adapted to support a grenade 30, the members must be placed under tension. In order to retain the supporting members under tension, a plate 31 c is mounted on theouter ends 20 and 21 of the supporting members 16 and 17. The plate has an opening 33 adjacent one edge thereof for receiving the end 21 of the member 17. has formed thereon, an elongated notch 35. A formed of sheet metal At its opposite edge, the plate 31 inwardly extending strip 36 preferably or like material is mounted in the rear of the notch and has an opening 37 formed therein by punching out a lip 38 from the body of the lip extends through the notch 35 back as shown at 39 against of the plate 31.

The strip 36 is secured to of the plate 31 by a connecti metal, such as soft solder. the fusible connection 40 mel strip. The and is bent the rear surface the rear surface on 40 of fusible In case of fire, ts or is softened to such an extent that the tension of the resilient supports it and 17 will cause the supports to spread apart and detach the strip 36 from the plate 31. As the resilient supports are released, the grenade will drop and break, thus extinguishing the fire. Furthermore, as the supports are released, the tension will cause the supports to swing about the pivot portions 25 thereof as shown in dotted lines in Fig. 8 and elbows 18 of the supports will exert a thrust against the grenade, forcing the grenade away from the wallas it drops. The impact of the elbows 18 against the frangible grenade will also tend to break the grenade and release the liquid.

1F rom the foregoing description it will be seen that a simple and practical grenade support has been designed and that this support will in case of fire, quickly release the grenade. Furthermore, it should be noted that the fusible element or connector is located in a position spaced from the Wall or other supporting structure on which the device is mounted and, therefore, will become heated and function more quickly than it would if the fusible element were located against the supporting bracket or plate 10 and in close proximity to the wall.

Although one specific embodiment of the invention has been particularly shown and described, it will be understood that the invention is capable of modification and that changes in the construction and in the arrangement of the various cooperating parts may be made without departing from the spirit or scope of the invention, as expressed in the following claims.
